Limitless Physique: Holder of this power will have no limit to his physical strength, durability, speed, agility, perception,vitality and all other attributes of a human body. However he will be limited by his inability to do things that are impossible for normal humans to do like flying, breathing underwater and space, typically in environments where normal humans cannot live.
But due to his limitless vitality he will not die even if he is thrown into environments where normal humans cannot survive, instead he will undergo hibernation until he is in a friendly environment.
During this hibernation, his body's cells will die continuously but the limitless vitality creates a new cell every time a cell dies and replaces it.
